IE7 is gaining market share and we can start to use more CSS3 selectors in our day to day code. Because of this, it’s worth a quick reminder that the more semantic we make our (X)HTML, the easier to implement the selectors will be.

For example, imagine the opportunities with the XFNmicroformat; by combining this with the partial attribute selector, you can add a little flourish to your pages.
Using these examples:

this seems very neat, but I’m not sure how usable it is quite yet. I manage a quasi-heavily trafficked site (about 3,000 visitors a month) and the stats are saying that IE7 is only used by 30% of IE users (15% overall). I’d estimate that about 55% of users could see the semantic code right now. I know some people who still haven’t gotten the auto update from Microsoft. Hopefully it’ll get out soon!
